An antimalarial agent used for the treatment and suppression of Plasmodium vivax, P. malariae, and P. falciparum; available as the phosphate and sulfate. It does not produce a radical cure because it has no effect on the exoerythrocytic stages; c.-resistant strains of P. falciparum have developed in Southeast Asia, Africa, and South America. It is also used for hepatic amebiasis and for certain skin diseases, e.g., lupus erythematosus and lichen planus.
